GREASE-CUP.

Specification of Letters Patent.

Patented N ov. 5, 1918.

Application filed November 12, 1914. Serial No. 871,646.

To all fao/tomy t may concern.'

Beit known that I, RALPH HAMILTON Birnen', a citizen of the United States of America, residing at the Hotel Majestic, 72nd. street and Central Park lVest, New York city, in the county and State of New York, U. S. A., electrical engineer, have invented certain new and useful Improvements in Grease-Cups, of which the following is a specification.

This invention relates to improvements in lubricators of the grease cup type, and aims to provide improvements therein.

In the present invention a grease cup is provided which may be filled without the removal or separation of the parts. The invention further provides a grease cup which may be readily filled, in which the liability of introducing dust int-o the cup is minimized, and which, when closed, acts to securely retain the grease, so that the grease will not escape except through the orifice leading to the part to be lubricated.

The invention further provides a grease cup which is simply constructed, and which can be cheaply manufactured.

Other features of importance will be pointed out hereinafter. 1

Embodiments of the invention are illustrated in the accompanying drawings, whereinA Figure 1 illustrates the grease cup in elevation.

Fig. 2 shows the grease cup in vertical section.

Fig. 3 shows the grease cup in elevation,

with parts in section, the grease cup being in the position for filling.

Fig. 4 is a horizontal section cup on the line --lk F ig. 2.

Fig. 5 illustrates a further embodiment, the cup being shown in vert-ical section.

Fig. G is a section on the line G-G, Fig. 5.

Fig. 7 illustrates a detail of construction applicable to any of the embodiments of the invention.

Referring to the drawings, A designates the cup proper, having a feed orifice a and one or more filling orifices a. B a cover. C designates a follower adapted to fit closely within the cup A, and adapted to be traveled or moved by suitable means, such as the rod D journaled in the cover and having threaded engagement with the follower C. A pin (l fitting partially in a groove cut in the rod, may be provided for of the grease designates preventing longitudinal movement of the rod D in the cover. A spring E adapted to bear upon the follower may be provided between the cover B and the follower. The cover B and cup A have interengaging means F, preferably of the continuous type, such as screw threads. The cover B also has a skirt or sleeve Z), adapted to telescope the cup A, and the cup A is provided with a seat or shoulder o2, against which a part, such as the edge of the skirt is adapted to fit. The interengaging surfaces of the parts a2 and Z1 are so formed as to make a close contact, forming a tight closure against escape of grease through the filling orifice a, under pressure of the follower C.

The follower C is of such a thickness, or the follower is so limited in its upward or outward movement, or both, that the cover B may be lifted, by unscrewing or otherwise, in such manner that the strip may expose the filling'orifiee, without involving a separation or removal of the follower C from the cup,'see Fig. 3. This feature is one of importance, inasmuch as in a construction, such as the present, where the follower fits closely within the interior of the cup, it is a diflicult matter to reinsert the follower into the cup, particularly when the follower is in its withdrawn position, as shown in Fig. 2 or 3.

When the interengaging means F are in the form of screw threads, the screw threads are preferably of such a length that the cover may be turned in such manner that the skirt b will expose the filling orifice a without the interengaging means becoming separated.

When the oil cup is located in comparatively inaccessible places, such as in certain parts of automobiles, it is some times diiiicult, in filling the grease cup, to have the filling orifice opposite the point of most convenient access. In order to overcome this difliculty, the grease cup may be provided with a plurality of filling orifices a', as shown in Figs. 5 and G. In addition, a ring G, having preferably asingle orifice g therein, may be provided to surround the row of filling orifices. The ring G is turned to a position to bring the orifice g thereof into register with the filling orifice a most convenient of access.

The skirt b is preferably arranged on the outside of the cup, and closes the filling opening or openings, when the parts are in closed position, as shown in Fig. 2.

Y 7, may be provided between the partsl Z/ and confined to the particular embodiments illus- Vtrated and described.
